Why does it always take several years for sexual accusers of famous men to press charges or even report it

I am guessing they are unprovable in many cases. But bringing it up to effect political change makes it an effective weapon. Who knows if this Plantner guy is guilty or not? He's no prince either way. But this last second accusation stuff is unsavory at best. The dems used them to stifle his donor funding thus eliminating him from the election even though he was chosen to represent democrats by the voters. What is it about democrat establishment giving the 🖕 to voters? It's becoming a habit with them. Standard operating procedure.
